Is this the end of my marriage?

[P17]

As usual after speaking to IC, I don't feel so great today so I'm thinking that perhaps the NC should start this weekend as it's as good a time as any. I'm still a little torn after what Sandi2 said before about there being no rush on it. It's harder some day than others though.

W contacted me yesterday morning telling me she is free on Wednesday to spend time with D and wants me to let her know what time is best to come around.

I have also decided to contact her family and CLOSE friends about the situation. I have come up with the following message:

"
Hello,

I am contacting you as a friend of W.

W is having an adulterous affair with a previous work colleague, OM, from <OM last place he lived>. These past 12 months of our marriage have been testing on both sides, with illnesses and fighting for contact with our D, but 7 years of love, commitment and support is a lot to throw away.

I have heard many stories about the reasons for the affair, none of which are true. When listening to them, please remind yourself that there are two sides to every story. So far I have chosen to keep my marriage private and not wash my dirty linen in public.

I love her, want to save the marriage and OM is a third party in the way of that.

If you care about W then please encourage her to make the right choices for her family.

Please feel free to contact me if you would like more information.

Many thanks,

BS
"

Feel free to take a large 2x4 to my head but I have heard so many stories that I am simply sick and tired of keeping quiet about them. Every one of them is utter nonsense and every one of them casts me out to be the bad guy - I know this is just W's rewriting of history but when do I get a chance to enough is enough? At the moment I've simply had enough.

The email above is just a very quick draft. I've tried to make sure it doesn't come across as weak but I'm no expert which is why I'm posting here.

My plan is to contact these people and then go NC.
